Practical Geography

The study of Practical Geography has got unprecedential importance in recent times. Though the technical and applied branches like Interpretation of Topographical, Weather Maps and Weather Data Analysis, Surveying and Area Measurement by GPS etc. are in much discussion today, the study of Practical Geography is equally important for obtaining regional information. This book is specially prepared for the students of Second Year B.Sc. Class (C.B.C.S.) of Kaviyatri Bahinabai Chaudhari North Maharashtra University, Jalgaon.
This book will prove to be useful for the studies of syllabi prescribed in other universities as well as preparations for the new syllabi prescribed for examinations conducted by Union Government and the State Government. Keeping these points in view, present book has been prepared to extend information regarding Practical Geography. This book contains the information regarding Interpretation of Topographical, Weather Maps and Weather Data Analysis, Surveying and Area Measurement by GPS etc.
